To @ZZ 107mm t mag/*concern Be it known that CHARLES H. MYERS,

poses, of which the following yis a specifi-v cation.A

This vinvention relates to that class of moitor cycles which are propelled by means of zin-explosive engine, vand has special refern I: cnc-e to means ior generating and supplying the combustiblogas -to the engine.

The invention'has for its object the -provision ofsimple and inexpensive means for generating the gas and preventing loss of the. volatile fluid from which 1t is formed,

while at thesame time providing for a con-l tinuous supplyof the gas.

These objects and such other incidental objects will hereinafter appear, are attain-ed by the use of the mechanism illustrated in the accompanying drawings, and the inventioneeonsists in certain novel fealtures ofthe same which will` be hereinafter first fully described and then more particularlyvpointed out inthe appended claims.

In the dravv'fings, Figure l is a perspective view of a generator constructed in ac- Fig. 2 is a longitudinal vertical section of the same.

Fig. 5 isI a detail perspective view of a portion of one oft-he wick holders. Fig. G is a detailperspective view showing amodified form of the invention. Fig. Tisl a transverse vertical section of such modified form.

The body of thegenerator consists of an elongated casing or housing l provided with taperedends, indicated at 2 and', to the apezres of vwhich are vsecured brackets or loops il: by neansfof which the devices may be secured in position upon the frame of themzmhine. Near the tapered ends of the body l provide the internal partitions or end plates '5, thereby providing compartments 6 at the endsof'the body of substantially triangular forinwhich may be utilized for lvarious purposes. ings, have shown one ofthese compartments vas used to contain lubricating -oil which may-pass through an outlet-pipe 7 ln the draw tothe engineer to other parts of the vehicle in order to lubricate the bearings and insure van. easy running machine. In order to utilize .these end/chambers, a plug 8 is fitted in the upper side of the same to permit the liquidlto be poured-thereinto. rlhe space between the end plates 5 is divided by a horizontal ypartition 9 into an upper reser- ,voir cr storage tank l0 and a lower generating compartment 51:1, as will be readily understood. (rfi iillingopening is provided inthe top.ofthebodyand this lilling opening is Vnormally.closed lby a plug or screw cap '13 :in order to permit a supply of volatile.iiuidtobe.poured into the tank, as will be readily understood. The user of the machine may beeasily informed vas-to whenfthe tank vhas been `filled `by reason of the 1fluid Overdowing through the said opening. In thefbottom of the partition@ is an opening through which the'tluid may pass to the generating' compartment, and this yopening jis normallyclosed by a stem lthreaded inra bearing 1G in the top of the tank and equipped with van operating handle 17, as shown andL as willbe readily understood. `When charging'the'device, this stem 15 Iis raised so as to establish communication betwee thetank A10 and thegenerating chamber ll, andthegasolene or otherhydrocarbon which is Apoured intofthe tank Vis then passed at once into the generating compartment. Vhenthe proper supply ofthe volatile vfiuid'l'ias been fed into the generating chamber, the stem lislturned inward so asto cut off-the flow into the said compartment andthe subsequent feeding ofthe fluid will proiido a reserve supply within the tank l0.

Within the generating compartment 11, I arrange a series of superposed pans or wick holders 18 which of a width slightly less tran the width of t-he compartment and are disposed so as to provide a tortuous air passage between and over the several pans land around the ends of the same. That is tosay, the pansare arranged so that the space duetothe difference in width between thc pans 'and the compartment will be arranged alternately at opposite sides of the pans. "Theside of the pan adjacent the saidopening is lower-than the opposite side oft-he pan, asindicated at. 19, andthis difference Vin"height of the sides ofthe pans pern'iits the air to pass from the space at the side of the pan into the space between adjacent superposed pans and so across the surface of the wicks 2O arranged within the pans. These wicks are preferably short lengths of woven wicking arranged 0n end transversely of the pans with their capillary passages vertically disposed. This arrangement presents the ends of the wicks to the passing air currents and utilizes the force of capillary attraction to bring to the surface every particle of the oil or other fluid with which the wicks have been saturated. It is to be understood, however, that this particular form of oil-holding material is not essential to the operation of the generator, although most satisfactory results have been obtained therefrom, and that any absorbent material may be used with good effect.

In order to prevent the air current passing over the wicking from sucking the same from its position within the pan, I provide a series of longitudinal rods 2l secured rigidly to the ends of the pans and passing over the wicking so as to securely hold the same within the pans. The pans are each supported by the next lower pan, and in order to acquire the necessary strength without undue weight, 1 provide within each pan a series of transverse partitions 22 which are preferably constructed of perforated corrugated sheet metal plates set on edge within the pans and rising to the full height of the ends of the same. These partitions consequently serve to support the superposed pans and also serve to direct the air currents squarely across the surface of the wicking so as to thoroughly act on the entire body of volatile fluid. A longitudinal partition 23 is arranged within the body of the device near one side of the same so as to form an air flue 24 communicating with the atmosphere and having an open lower end near the bottom of the body. As shown most clearly in Fig. 4i, this air flue leads directly to and upon the lowest pan or wick holder, which is of the full width of the body of the device so as to extend entirely across the same. The air is admitted to the air iue 24 through a series of openings 25 provided on the side of the device, which openings may be controlled by a screw cap or other device 26 and are preferably equipped with a screen 27 so as to filter the air and prevent the entrance of dust and other deleterious matter to the generating compartment. The air is drawn through -the said openings into the air flue by the suction of the engine and passes down to the lowest pan or wick holder and transversely across the same, and then upward in a tortuous course over the successive superposed pans, escaping through an outlet pipe 28 which is preferably disposed slightly above the uppermost wick holder or vaporizing pan and communicates with a small discharge chamber 29 formed by an offset 30 in the partition 9, the said chamber serving as a means for creating a vapor cushion which will receive the pulsations of the engine and prevent the same being transmitted to the wick holders so as to disturb the wicks and to that extent interfere with the successful generation of the gas. through the pipe 28 to an air and gas mixer 3l equipped with a back-tiring escape valve 32 and then passes through a pipe 33 directly to the explosive chamber of the en- Ome. Y

b In filling the generator, the oil is fed directly onto the wicks in the uppermost pan or wick holder and will saturate the same and then overflow onto the next lower pan,

ythe wicks in which will be saturated, after which the surplus oil will overflow therefrom to the next lower pan, and this operation will be repeated until all of the wicks except those in the bottom pan have been saturated. As soon as the oil or other volatile Huid begins to pass into the wicks in the bottom pan, a dripping of the fluid through a stop-cock 34 depending from the bottom of the generator will be noticed and the operator then at once manipulates the rod 15 to cut oif the flow and closes the valve 34 so as to prevent loss of the fluid, the pouring of the fluid, however, being continued until the storage tank or reservoir is full. The engine, having been started, air will be drawn thro-ugh the generating compartment in the tortuous co-urse described and will Vaporize the oil at the surface of the several wicks, the vapor thus created being carried into the combustion chamber of the engine and there exploded to drive the engine. Should the engine begin to work improperly or give notice of diminishing supply of vapor, the rod 15 is manipulated to permit a tiow of the fluid from the storage tank 10 to the generating compartment so as to replenish the supply therein, and the stopping of the engine is thus avoided.

lt will be noted that the wicks in the bottom pan are not permitted to become saturated when the iiuid is fed into the generating chamber but the feeding of the fluid is arrested as soon as a dripping from the bottom pan is noticed, and this dripping will occur as soon as any iiuid is fed to the wicking therein, inasmuch as the drip-cock 34 depends from the bottom of the said pan. This bottom supply of wicking, however, serves to catch and hold any fluid which may be thrown from the upper pans by the vibration of the machine during its travel, and the fluid thus caught and absorbed by the said wicks will be vaporized by the incoming air, as will be understood.
